MS Outlook Updates

When i accepted the recent update for MS Office including Outlook, it wiped out all my contacts set up on my computer.

It also seemed to affect the Main Identity settings as it wiped those pretty much also.

Is there a way that one can save all these things, as i actually fear having to turn my computer off, which i know i will be doing when i fly next!

Any help on this would be real;y appreciated.

Thanks
